The complement of the Boolean expression is:
The complement of the Boolean expression $a \cdot b' + a' + a' \cdot b$ is:
- (a)$a + b' \cdot a' \cdot a' + b$
- (b)$(a' + b) \cdot a \cdot (a + b')$
- (c)$(a + b') \cdot a' \cdot (a + b')$
- (d)$a' \cdot b + a + a \cdot b'$

Correct option: (b)
Answer: (b) (a' + b) • a • (a + b')
By De Morgan's laws: (a • b' + a' + a' • b)' = (a • b')' • (a')' • (a' • b)' = (a' + b) • a • (a + b').
